In 2019 scientists unveiled The first pictures of a black hole, M87*. These observations started a wave of new studies on how black holes work, how they grow and how they change. And now, after a few upgrades, the Event Horizon Telescope Network is back with another bomb that focuses on M87*.
In a number of pictures of the EHT between 2017 and 2021, scientists observed a completely unexpected reversal of the magnetic fields of the black hole – in other words, their polarization turned. They also discovered strange jets that spread out of M87*. The observations offer researchers their most detailed view of the black hole and possibly as a result of the extreme conditions that surround it. The results should be detailed in an upcoming appearance Astronomy and astrophysics paper.
“These results show how the EBE develops into a full -fledged scientific observatory that is not only able to deliver unprecedented images, but also to build a progressive and coherent understanding of the physics of black hole” release.
Unexpected changes to a super massive black hole
M87* is a super massive black hole that is located in the middle of the Galaxy M87 and is about 55 million light years away from the earth. This giant is an estimated more than six billion times the mass of our sun. Such a gigantic black hole should have a large gravitational influence on any matter, as can be seen in the ring of the bright, orange plasma in the picture.
However, what surprised astronomers, however, were technically known as a polarization pattern in the direction of the Plasma spiral around M87*. It indicates that the area around M87* is a “developing, turbulent environment, in which magnetic fields play an important role in the government how matter falls into the black hole and how energy is started outwards,” explained the researchers.
“It is noteworthy that the ring size has remained consistent over the years and has predicted the shadow of the black hole through Einstein’s theory,” the polarization pattern, “said Paul Tiede, co-lead author and astronomer in the center for astrophysics in Harvard & Smithsonian.
“This tells us that the magnetized plasma near the event horizon is anything but static. It is dynamic and complex and presses our theoretical models to the border,” he added.
A piece of the cosmic puzzle
The observations suggest the polarization pattern at M87*, which was turned over in 2017 before climbing in the other direction in 2021.
“It emphasizes our models and shows that we don’t understand much yet near the event horizon,” said Jongho Park, another co-author of the newspaper and astronomer at Kyunghee University in South Korea.
The physics of the black hole is a bit like a black hole, with countless unanswered questions and secrets that still have to be solved. Every hint we can get helps to bring our science forward: super massive black holes like M87* are of essential importance for the formation of stars of galaxies and they help to distribute the energy of energy throughout the universe.
In particular, the mighty jets, which are emitted by such large black holes, are a “unique laboratory” for astrophysicists who examine gamma rays or high -energy neutrinos, the researchers said that they offer a large selection of information about the role of black holes in cosmic evolution.
